The high-precision Penning-trap mass spectrometer PENTATRAP is currently being commissioned at the Max-Planck-Institut für Kernphysik, Heidelberg. PENTATRAP aims at mass-ratio measurements of single stable and long lived highly charged ions with a relative uncertainty of a few 10−12. At this precision level, PENTATRAP will, for instance, contribute to electron-neutrino mass related measurements within the ECHo collaboration, which determines the de-excitation spectrum following the electron capture in 163Ho. PENTATRAP will determine the mass ratios of the desired ion species through measurements of their respective cyclotron frequencies in the strong magnetic field of a Penning trap. The experimental setup consists of five Penning traps, making simultaneous storage of several ion species possible. This allows for in situ calibration and reference measurements. The current status and outlook of the experiment will be presented in the poster.
